Title:
ＰＨ測定装置の較正ずれの特定
Document Type and Number:
Japanese Patent JP6893208
Kind Code:
B2
Abstract:
The invention relates to a comparison unit (130) configured for determining if a first pH measuring device of a first tank (104; 106) is affected by a pH-measuring problem, the comparison unit being configured for:- receiving a first CO2 concentration and a first pH value, the first CO2 concentration being a CO2 concentration of a first gas volume above a medium in a first tank, the first CO2 concentration and the first pH value being measured at a first time when the medium in the first tank is in pH-CO2 equilibrium state with the first gas volume and before said equilibrium state is modified by the metabolism of a cell culture in the first tank, the first pH value being a measured value provided by a first pH measuring device operatively coupled to the first tank (102);- receiving a second CO2 concentration and a second pH value, the second CO2 concentration being a CO2 concentration of a second gas volume above a medium in a second tank, the second CO2 concentration and the second pH value being measured at a second time when the medium in the second tank is in pH-CO2 equilibrium state with the second gas volume and before said equilibrium state is modified by the metabolism of a cell culture, the second pH value being a measured value provided by a second pH measuring device;- comparing the first and second pH values and CO2 concentrations for determining if comparing (206), by the comparison unit, the first and second pH values and comparing the first and second CO2 concentrations for determining if the first pH measuring device is affected by the pH-measuring problem.
